Thanks for checking this out and for giving so much feedback!
On performance: it's definitely a struggle to work out how much optimisation to put in place at different stages of a project. This build had some culling etc. in place to enable the map building. Gleb [our other programmer] also pushed a hotfix to address an issue where some hybrid laptops were not having their GPU detected by GameMaker. But yeah, the project was not really at a stage of proof where I would be concerned about extended the playtesting reach beyond "hey, play it if you can!". We'll definitely set the settings lower by default in future builds - and do further optimisation. I think a recurring issue we're also going to have is just people expecting any 2D game to run on anything, because they think the job of a GPU is to render realistic 3D graphics... I don't think we're going to escape from that no matter how much we do.
All of your UX/controls feedback is valid. We haven't dropped an update in a few months but the next one with have key rebinding (it's already in, we're just not updating the build until some other stuff is ready as some of the core design has pivotted a lot). I wouldn't necessarily think of myself as console-first, but I do tend to play character/action-driven PC games with a controller, and when it comes to platformers I have a hard time empathising with keyboard players! The next build will have better controls generally - and some of the contextual long-presses will be gone as the teleporter concept is leaving the game in the next stage of design changes. There's also some wonk around the character controller where sprinting momentum doesn't transfer to jumps etc. which is on our list of things to address.
I really appreciate you taking the time to play and I hope if you play the next update it'll work better for you! The only reason it's taking so long is that this was always a strange design and it's only really in the last 2 months that certain aspects of the loop have come together in a way which makes it easier to see what the final game might be.
